Application filed March 6, 1923. Serial No. 62.31.216.

concern. I, JAMES B. QUieLnY, a and a resident in the county of Jackson,Missouri, have invented certain new and usetul Improvements in KeyRings, of which the following is a. speeitication.

This invention relates to improvements in key rings.

The object oi"v the invention is a key ring which to provide isexceedingly easy to n'ianipulate for locking a key thereon or releasingthe saine.

lt is also within of the invention th ingly Simple in cons tomanufacture.

Other objects rel the scope of the objectsV at the device beexceedtruction and inexpensive ating to details of construction willhereinafter appear in the detailed description to follow.

The invention is ilhiistrated by way et example in the accompanyingdrawings, in

which:

Figure 1 vice and showing conventional torni showing a` key locke is aperspective view of the dethe saine attached to a. of split ring andalso d thereon,

Figure 2 is a longitudinal sectional view or' the device, and

Figure 3 is a view in side elevation of the device, the body portionthereof shown in longitudinal section in order to clearly ilj lustratethe workin vice.

g mechanism ot the de Referring to the drawings more particularly, 1t)indicates generally a stein which is provided with an enlarged bore 1lter- 12. fitted a Y at its upper end in a reduced bore lV'ithin the bore12 there is slidably pin 13, said pin terminating at its lower lend in acircular head 14 which is foi-ined with-a. V-shaped lug 15, said lug Ybeing' in axial alignment with the pin. v'l'he reduced bore ll pr ovidesa' shoulder at its open end, as indicated at 16. and interposed betweenthis shoulder and the head 14 oi the pin 13 is a coil spring 17. saidcoil spring` as is apparent being adapted to urge the pin 13 downwardlywith respect to the stein 10.

Slid able upon the said sleeve carries stein 10 is a sleeve 1S and a pin19 which. is disposed in longitudinally extending` slots 20 formed inthe stem 1() and also extends through a suitable opening in the pin 13as best shown in Fig ure 2 of the drawings.

As is obvious thesleeve i8 when moved upwardly upon the stein 1t) willcarry therewith the Vpin 1B against resistance of the spring 17.

it 21 there is indicated a pair of semicircular jaws, each jawterminating at its one end in a laterally disposed lug 22 and each lugbeing pointed, as shown. The end of each jaw 21 which terminates in thelug is flat and in the lower end ot' the stein l0 there is provided apair ot' diametrica-lly oposed recesses 23. The lug portions 22 of thejaws 21 are fitted upon each other and inserted in the lower end ot' thestem 10, and pivotally connected to the stein by means of a transverselyexteiiding pin or rivet 24. The recesses 23 permit the jaws to be swungupwardly or outwardly in the dotted line position shown in 'Fig 3, andthereby to pei-init one or more keys to be placed upon the saine. 'lhefree end ot' each jaw is provided with aii oit'set, so that the jaws mayoverlap each other when brought to the closed position as illustrated inFigures 2 and 8. The jaws may be of any desired cross section, however,preferably circular vas shown, and either jaw is adapted to be extendedthrough the usual opening provided in the handle portion of a key. A keyof this kind is shown in Figure l and indicated by the reference numeral25.

The stem 10 may also be formed at its one end with av ring 2G andthrough this ring there may be threaded a split ring 27 of the usualconstruction, whereby the keyliolding device may be secured to a chain.

In the usc ot the present device, assuming av key placed upon one otthe'jaws 2l and that the jaws are closed, as shown in Fig. 1 the pin 13will bc in the position 95 shown in Fig. 2l and the V-shaped lugr 'l5will engage between the pointed lugs 22 ot the jawsQl and thusI lock thejaws against movenient with respect to cach other. The lugs ot the jaws2l should register with each other when said jaws are closed upon eachother. The spring 1T will at all times retain the pin 13 in this lastnamed position.

lt' it is desired to remove the key from the jaws 21 then the sleeve 1Smay be grasped and inoved toward the ring 26 upon the stein 1t). wherebythe pin 13 will be moved so that its lug 15 will release the lugs andthus permit the jaws to open and in this way permit a key to be removedfrom said lio jaws. As is obvious the locking mechanism for the jaws 21may be operated in an instant either to release or lock said jaws. i'

It may be here mentioned that this particular device is valuable to thedriver of an automobile in ease that the automobile should haveasteering wheel lock where two keys must be employed simultaneously for`unlocking the same. In such a case, the keys must be separated fromeach other, that is, both keys could not be used upon the. same ring,and by having a key ring which maybe quickly operated for releasing akey it would be of an advantage, as is apparent.
